Life In 19x19

The position above is taken from 9-year-old Nakamura Sumire's game against Choi Jeong. I read about some very interesting comments from various onlines sources.

Commenting on , Shiraishi Yuichi 7-dan of Japan said something like (I translate roughly): "it's not easy for the child to play such a move, attacking white while defending her own weakness. Satisfying both requirements, this is professional thinking..."

It was reported (I could not confirm the source though) that Yoda Norimoto also spoke highly of this move.

On the other hand, commenting at Yikeweiqi, Chinese professional Yang Dong 4-dan said (also my translation): B55 (R9) is a clueless move. At this moment, either crawling at S11 or enclosing at P10 are more viable solutions. For a girl under 10, B55 is probably not considered a serious error. However, if measuring using professional standard, this move is completely inadequate.

AI appears to support the Chinese view (see viewtopic.php?p=240866#p240866 showing a 10% drop of winning rate for black).

My English view was it was a bad move, it seems pretty trivial to note that q8 ends up misplaced. If you want to play something defensive and thought p10 was too thin then p9 would be my next idea. Also I thought q14 at r15 would be better: with the game line black's group isn't locally alive whilst white got more eyespace.

I have noticed recently that some dual purpose moves do not meet the bots' approval. Sometimes they don't achieve either purpose very well.

===>This could be something in generating move that Japanese pros are different from Chinese or Korean pros. I mean that Japanese pros put more stress on good shape than on practical moves, thus less flexible in choosing moves, which some says one of reasons that they have relatively lower winning rates than Chinese and Korean competititaters

I wonder if the Japanese commentators praised the actual value of that move (as in "one of the best choices"), or rather the spirit of that move ("pro thinking") even if it was not the best choice.
